Re: I have question about VASB inputfile

[Wenbin Yu]

You have the freedom to choose your own coordinate system. You  just need to be consistent to use one single unit system for one input.
You have the freedom to choose your own reference line. It could be your centroid, neutral axis, elastic axis, mass center. If you don't know these points, you can choose an arbitrary reference line, run VABS once to calculation these centers then shift the coordinates to one of the references you like to rerun VABS.

Dear Prof Wenbin Yu

How are you ?

I'm NamKyung Yoon, I have qustion about setting about VABS

I was runned your example files. But I can't not find options flags which

determines Units(SI/US), reference line-calculation cross-sectional properities

about elastic axis or aerodynamic center or centroid.

I have to know above things because I'm using DYMORE, and I want to put the VASB's

result into DYMORe.

Please let me konw these option flag settings.

Thank you

Best Regards.

For element 61, the order of numbering is wrong. The nodes are numbered clockwise. In VABS, the nodes should be numbered counterclockwise.

Dear Professor Wenbin Yu

I have problem with Box-Beam mesh error that is generated in Patran

(Folder :: Patran Modeling Files)

I encountered Jacobian error  in 61th element

(Folder :: VABS input file)

So, I runned subelement (1st~60th), it is Okay !

(Folder :: Sub element Execution In VABS)

What should I do to slove this mesh problem?

Thank you

Best regards

In finite model, it can be solved to change element normal direction.

Like patran or other FEM tool, it is easy.

Thanks.

Thanks a lot for helping answering.
